" big 3 ?? " amp wire size ?

Hi i have an saz 1500 and a sax 100.4 I was thinking about doing the big 3

is it ok to use 4 ga. ?

and when i run the power wire to the back of my truck for the amps should i run 0 ga. and if i do 0 ga to the junction should i run a 4 ga to each amp from there or just run 0 ga all the way ?

also you think a 1800 battery is good enough or should i get a 2400 " i am running 2 compressors for my air bag system " and im going to get a 130 amp alternator

thanks a lot for any help .

bought sax 100.4 from Ny_Vibe on caco and 2 sa 8 from topdawg on caco " well tried to but he is a d bag " bought saz 1500 from Black Truck 10 on caraudio.com , im type34me on ebay and if you need more info hit me up thanks

Re: " big 3 ?? " amp wire size ?

You want the same size wire in your Big 3 set up as you are running from amp to disto block. I also agree with yousing the 1/0 welding cable it has a nice heavy jacket and is designed for Hi-current application. Un-like audio cable the welding cable is manufactyred according to the National Electrical Code and has to follow the requirements of them.
